Answer:

Step-by-step explanation:
Hi there!

Solve -2^2:

Divide both sides by -4:

Subtract 10 from both sides:

Divide both sides by -5:

Therefore, x = 7.
I hope this helps!
We have to take out the greatest common factor from the given polynomial to factorize the expression. If you observe the terms of the polynomial, the greatest factor that is common to all the terms is

. So taking it out as common, the factorization of the polynomial will be:

So the option C gives the correct answer
Answer:
9
Step-by-step explanation:
Answer:
The number of rotations completed by tire = 500.
Step-by-step explanation:
The diameter of the tire of toy car = 8 cm
Now, DIAMETER = 2 x RADIUS
So, radius of the tire = D/2 = 8/2 = 4 cm
Now, Circumference of the Circle = 2πr
= 2 x 3.14 x 4 = 25.12 cm
Now, 
= 
The number of rotations completed by circle = 500.
